Amiga Compilers¶

The Amiga compiler-side toolchains documented on this wiki:

SAS/C v6.58 — the C compiler and full development environment bundled with the NDK 3.x era. Tree: 13 articles covering compiler, editor, debugger, utilities, assembly, optimization, portability, and the system library reference.
VBCC — Volker Barthelmann's open-source optimizing ISO C compiler, actively maintained, with permissive commercial-use licensing for M68k + AmigaOS targets. The modern replacement for SAS/C.
CatComp and Installer — the catalog compiler and the Installer scripting language, used to localize and distribute AmigaOS software.
